I wanted to share a trick I didn’t see on AppImages website, when preparing an appImage for freewrl.sf.net using the Manual approach:
I was looking for where to store local resources not compiled in -in my case font files- and found a trick that seemed to work from main.c:
char * libpaths = getenv(“LD_LIBRARY_PATH”);
And that returned a long string containing:
/tmp/.mount_freewrz81ycQ/usr/lib/:
/tmp/.mount_freewrz81ycQ/usr/lib/i386-linux-gnu/:
/tmp/.mount_freewrz81ycQ/usr/lib/x86_64-linux-gnu/:
…
So I took the first of those, stripped the /lib/: and added my resource folder path /fonts and used that in my program as an absolute path to the fonts, put my fonts there in .AppDir and it worked. Q. how reliable is that?
